Product Safety Notice; Specifications - Hitachi CM821FET Service Manual

PRODUCT SAFETY NOTICE

Many electrical mechanical parts in the color monitor
units have special safety related characteristics.
These are often not evident from visual inspection nor
can the protection afforded by them necessarily be
obtained by using replacement components rated for
higher voltage, wattage, etc. Replacement parts which
have these special safety characteristics are identified in
this Service Manual.
Electrical components
identified by marking with
the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
manufacturer recommended replacement one, shown in
the parts list in this Service Manual, may create shock,
fire, X-radiation, or other hazards.
Productions are issued from time to time. For the latest
information, always consult this Service Manual.
